The Greymarch can be thought as the Discordian version of Persephone myth. Eris and Aneris's brother, Spirituality, travels back and forth between Order and Disorder, causing the principle of Chaos. He actually has two names, depending on with of his sisters he is with. Sheogorath is Spirituality when ruled by disorder. Jyggalag is Spirituality when ruled by order. Since Daedra are subject to a reincarnation cycle, This “Daedric Prince of Spirituality” is doomed to relive the endless cycle of the Greymarch.
